A fresh hit of mint + lime that won’t spike your blood sugar (or wreck your ketosis)
✍️ I Used to Avoid Mojito
Because honestly, between the sugar and the bloat from club soda, they felt like a guaranteed crash. But one night at a bar, my husband asked for a mojito “no syrup, just lime, mint, and soda.” Game. Changer. We tweaked it at home with white rum and a sugar-free simple syrup—and it’s now in our Friday night cocktail rotation.
💡 Why This One Works So Well
- Zero added sugar = no insulin spike, no fat-storing signal to your body.
- Mint + lime + sparkle feels like the real thing, without the metabolic consequences.
- White rum is a clean liquor—0 carbs, doesn’t mess with your ketones directly.
- Satiating enough that I don’t feel like binge-snacking after (huge win).
🧾 What I Used (And Why It Worked)
- Lime juice (6 tbsp) – Adds punchy acidity. About 2g net carbs per 1 tbsp, so portion matters.
- Fresh mint (16 leaves) – Bright, aromatic, and no carbs to worry about.
- White rum (3 oz) – 0g carbs, clean burn. Tequila works too if you’re more into that.
- Ice (2 cups) – Helps stretch the drink and slow you down.
- Sparkling water (1 cup) – Fills the glass, keeps it crisp without sugar or calories.
- Wholesome Yum Zero Sugar Simple Syrup (optional) – Monk fruit + allulose, zero net carbs, no weird cooling aftertaste. I’ve made my own before but this one’s honestly better than what I could whip up.
🔁 Keto Swaps That Actually Work
| Swap | Result |
|---|---|
| Use tequila instead of rum | Brighter flavor, slightly drier finish |
| Skip the syrup altogether | Totally fine if you’re a tart cocktail lover |
| Add cucumber slices | Makes it even more refreshing, adds zero carbs |
| Use flavored sparkling water | Just make sure it’s unsweetened (like LaCroix or Spindrift without juice) |
⚠️ Keto Missteps and How I Fixed Them
| What Went Wrong | Why It Happens | Fix |
|---|---|---|
| Too much lime juice | It adds up fast in carbs | Stick to 3 tbsp per drink max |
| Over-sweetening | Even keto syrups can feel heavy | Add a little at a time—taste as you go |
| Used tonic water | Sneaky sugar bomb | Use soda water or sparkling mineral water only |
👩🍳 How to Make It
- Muddle lime juice + mint in two glasses. You want the oils released but not pulverized.
- Add a mountain of ice—this makes it sippable, not chuggable.
- Pour in 1.5 oz rum (or tequila) per glass.
- Top with sparkling water and stir with a straw or spoon.
- Add syrup only if needed—some people prefer the fresh, tart version.
- Garnish with lime wedge + mint, if you’re feeling fancy.

🧠 Keto Cooking Tricks That Help
- Pre-portion your liquor. I keep little 1.5 oz shot bottles of rum ready so I’m not eyeballing.
- Batch your mint + lime. Muddle it in advance and chill so it’s ready for guests or cravings.
- Make freezer “mojito cubes.” Mint + lime juice frozen in ice trays = fast drinks.
🧊 How I Store and Track It
This doesn’t keep well once mixed (sparkle dies fast), but:
- I freeze leftover lime juice in 1 tbsp cubes
- I track this drink in Carb Manager as “homemade mojito – sugar-free”
- I label it as “social drink” so I can note if it caused stalls later in the week
❓ Keto Cooking What-Ifs (Answered)
Will this spike blood sugar?
Nope—not if you skip the sugar and use sugar-free syrup.
Can I use diet soda as a mixer?
You can, but IMO the artificial sweeteners can bloat and mess with cravings. I stick to sparkling water unless I’m really craving something sweet.
Is white rum keto?
Yes—0g carbs, no sweeteners added. Just don’t confuse it with flavored rum (which usually has added sugars).
Can I skip the syrup?
Totally. It’s honestly delicious without, especially if your tastebuds are already fat-adapted.
